Implantation bleeding and positive HPT?

you might just need to wait a little longer to test, ive read a lot of women get negatives till a little later. Right now I'm going through the same thing. I've had what I believe is implantation bleeding for the last 5 days...it's just a little brown discharge only when I wipe, and I've also been having some mild cramps this whole week as well (nothing compared to my usual period cramps)...My period is not due until Sunday, but I'm still getting negatives, the suspense is killing me!! good luck to you!!
